coxae not exceptionally large, hind tibiae toothed externally. It 

 differs from the characters that Licordaire assigns to Choei'idium 

 (and Scatimus, which he places beside Choeridiuni) by the very 

 decidedly dilated first and second joints of its labial palpi, and 

 also from Choeridinm (I have not a specimen of Scatimus for 

 comparison) by the apex of its front til)iae not truncate, by 

 the strong teeth of the external margin of its posterior 

 tibiae (which are much like those of Coptodactyla), and by 

 the very much more strongly dilated basal joint of its pos- 

 terior tarsi. The non-truncate apex of the front tibiae would 

 seem to forbid this insect being placed in the sub-group of 

 the Scatonomides which Harold names the Choeridiides, but 

 it certainly has many structural characters of that sub-group, 

 and I know not where else to place it. The presence of a 

 minute scutellum appears to be a remarkable character, but in 

 this it is closely approached by Coptodactyla, in which the 

 scutellum is perfectly visible (although it does not quite rise to 

 the dorsal surface of the elytra) when the prothorax is not quite 

 in contact with the base of the elytra. Two genera of Scatono- 

 mides have previously been reported as Australian — -Pedaria, to 

 which Harold refers Aphodius geminatus, Macl., and Coptodac- 

 tyla, which (as Harold has pointed out) is a Choeridiid, notwith- 

 standing Lacordaire's having treated it as a subgenus of Copris. 

 I may say, in passing, that I am not altogether satisfied with 

 Harold's reference of Aphodius geminatus to Pedaria, inasmuch 

 as its ventral sutures appear to me to be perfectly well defined, 

 but as I have not an authentic specimen of Pedaria (other than 

 A. geminata) for comparison, I am not in a position to deal with 

 the matter confidently. The present genus differs from Copto- 

 dactyla and Pedaria by inter alia iiuilta the non-truncate apex of 

 its front tibiae.
